The provided keyword term is not a single grammatical unit and thus does not have one specific part of speech. It is a composite phrase comprising two proper nouns in apposition ("Patriot Day," "September 11") and an independent clause ("we will never forget"). For the purpose of establishing a main point for an article, the central grammatical elements are the proper nouns, which identify the specific event and day of observance. These nouns function as the primary subject matter.
A detailed grammatical breakdown reveals the components of the phrase. "Patriot Day" is a proper noun, the official name of the U.S. observance. "September 11" is also a proper noun, a specific date that has become a synecdoche for the terrorist attacks. The two nouns work together to specify the topic. Following these is the independent clause "we will never forget," which consists of a pronoun ("we"), a modal verb phrase in the future tense ("will forget"), and an adverb ("never"). This clause serves as a declarative statement or a thematic motto, providing the emotional and commemorative context for the nouns. The entire phrase functions collectively as a slogan or thematic title rather than a standard grammatical construction.
In practical application for an article, the "main point" is not a single part of speech but the concept these components represent. The article's focus would be thematically driven by the action described in the clausethe act of remembrance. The nouns "Patriot Day" and "September 11" ground this theme in a specific historical context. Therefore, the main point of the article is the theme of national remembrance for the events of September 11, with the nouns serving as the concrete subject and the clause defining the article's perspective and purpose.
